ThomasVDD @ instructables.com writes: A while back I built a powersupply from an old ATX PSU, and while it works great, I wanted to step up my game with a digital powersupply. As already said, it is powered by batteries (2 lithium cells to be precise), and it can deliver a maximum of 20 V […]
Orthrus – SD card secure RAID USB storage
https://www.electronics-lab.com/orthrus-sd-card-secure-raid-usb-storage/
Nick Sayer @ hackaday.io build a SD card RAID USB storage board. He writes: This project is a hardware mechanism to provide secure “two man control” over a data store. It is a USB microSD card reader, but it requires two cards. The data is striped in the style of RAID 0, but the data […]

In 1982, the UK’s best selling computer, ZX Spectrum, was released by Sinclair as 8-bit personal home computer highlighting the machine’s color display. And today, a group of makers are introducing the Spectrum Next, an updated and enhanced version of ZX Spectrum. The Spectrum Next is fully compatible with the original one. It has been enhanced to provide a […]
PICTIL – Remake of the TIL311 hex LED display
https://www.electronics-lab.com/pictil-remake-til311-hex-led-display/
Yann Guidon @ hackaday.io rebuild the TIL311 hexadecimal display using a pic microcontroller. He writes: The TIL311 is a nice but expensive, obsolete, power-hungry hexadecimal display. It would be cool to make a tiny module with similar functionality which solves its shortcomings. A 20-pins PIC is a solution but other decoding chips could work too. […]

RX/TX sequencer
https://www.electronics-lab.com/rxtx-sequencer/
Lukas Fässler has designed and built an RX/TX sequencer based on a PIC16F18325, that is available on github: Much like the beacon keyer presented here earlier, this RX/TX sequencer is a simple but useful little device. Its typical use is in ham radio applications when a separate power amplifier (PA) and/or a sensitive low-noise pre-amplifier (LNA) is used. […]

Segger Microcontroller is known for J-Links device about debugging and programming lots of architectures: ARM, Microchip PIC32 and Renesas RX. Segger provides a lot of other software and hardware tools for debugging and programming purposes; SystemView is one of these tools. SystemView gives a complete insight of what is going inside the MCU graphically and […]
SHA2017 Badge — A Hackable Conference Badge with E-paper Display
https://www.electronics-lab.com/sha2017-badge-hackable-conference-badge-e-paper-display/
The hackable electronic conference badges are more and more being adapted in technical conferences and especially those for hackers and makers. These badges can be reprogrammed easily and could be used later as a development board. It’s not the first time to hear about a hackable badge; for example, Parallax has an open source one […]
